The original pressing hasn't got any tracks titles, it's a white label limited to few hundred copies. The release with the tracks name is a bootleg made by thieves, who ripped off Theo's music.
Actually, it's a Harold Melvin and the Bluenotes sample from the "The Love I Lost"...not sure if Teddy Pendergrass covered it. It's a firing edit though, love the frequency sweeps and distorted bass. Danny Krivit edits are also worth seeking out.
"The Love I Lost" is by Teddie Pendergrass. This re-edit is done in a style which reminds me of some re-edits on Ron Hardy's mixtape's from the mid '80s.
